Frequently Asked Questions About Casein Protein Powders

What is Casein Protein?

Casein protein is a complex protein found in dairy products. Foods with casein protein include milk, greek yogurt, cheese, and other dairy products.

Natural casein protein is also found in trace amounts in some processed meats and seafood, but it’s primarily found in dairy. Of all the casein protein foods, cheese has the highest concentration.

Casein is important for bodybuilders because it is absorbed slowly by the body. Unlike whey protein, which digests very quickly, casein takes up to 7 hours to fully digest. Whey protein absorbs/digests at a rate of 8-10g per hour, while casein digests at a rate around 5g per hour.

This slow absorption is very useful for a number of reasons. First, it helps keep you feeling full for several hours. For those on restrictive diets, this can be very beneficial in helping to avoid hunger cravings.

Second, it keeps your muscles fed with amino acids for several hours, which can help them recover more efficiently, and protect them from damage. Many bodybuilders take casein protein before bed to keep their muscles fueled throughout the night.

What Are Casein Protein Powders?

Casein protein powders are simply pure casein protein extracted from milk and processed down into a fine powder. Generally, the powder is then flavored and sweetened, and may or may not be mixed with other forms of protein (such as whey or soy) to make the finished product.

These products will provide a solid dose of natural casein protein in an easy, convenient package. Instead of having to eat large quantities of dairy products, which are high in fat and cholesterol, these casein powders give you a concentrated dose of pure protein. And since you might need more protein than you think, having an easy way to increase your daily intake is important.

There are typically two types of these supplements: pure casein protein powders, which contain only casein protein and flavorings, and protein blends, which contain a variety of protein sources, often including casein, whey, soy, egg, etc. proteins.

What Are the Benefits of Casein Protein?

To fully understand all the positive attributes of these supplements, you should understand the benefits of protein itself. Here are some of the benefits you may experience from protein:

  • Helps build muscle
  • Keeps your muscles fueled with amino acids for 5+ hours
  • Helps post-workout recovery
  • Helps repair muscle tissues
  • Helps stimulate muscle growth
  • Helps make dieting easier
  • Helps you feel more full
  • May help muscle soreness
  • Easy way to increase protein intake

Casein protein is a milk-derived protein powder that is popular among athletes and weightlifters. It has a variety of potential benefits and uses, including:

Protein Content

A standard casein protein supplement will typically contain 20+ grams of protein. That’s more than 1/3rd of the daily protein intake needed for the average person. And for those on high-protein diets, it presents an easy way to increase protein intake in an affordable manner. Casein is also a complete protein with a good amino acid profile.

Muscle Breakdown

Casein is a slow-digesting protein, which takes your body a lot longer to digest than whey protein and other protein sources. For this reason, casein is considered “anti-catabolic”. When taken after exercise, it helps to feed your cells with a steady stream of amino acids. This can help your cells synthesize protein in times where you would normally be breaking down muscles to keep cells fed, such as when you haven’t eaten in a while.

One in-depth study looked at the absorption rates of whey and casein protein. It found that whey protein caused an initial spike in amino acid levels, followed by a short-lived ongoing stream of aminos. Casein on the other hand, caused a smaller initial spike, followed by a long and steady flow of amino acids.

Another study found that participants given casein protein reduced the total amount of protein burned for fuel over a 7-hour period, resulting in an improved net protein balance (a key factor for muscle growth).

Muscle Growth

Casein is very effective for stimulating muscle growth, when combined with  strength training. It contains all the essential amino acids, including a high concentration of leucine – which is key for muscle protein synthesis. Leucine is considered a trigger for the anabolic muscle-building process.

If you have a low to moderate dietary intake of protein, taking casein protein can boost muscle growth simply by increasing your protein intake. Additionally, casein helps to protect muscle mass long-term, by reducing protein breakdown at night and during extended periods without food. It’s particularly effective when taken at night, as it helps keep your muscles fed during rest.

One study found that participants given a casein protein shake before bed helped to increase muscle mass and strength gains following exercise.

Other Benefits of Casein Protein

Casein may have some other benefits, although these are less rigorously studied. Some studies suggest that casein may have immune and antibacterial benefits. Another found that it may help to lower triglyceride levels.

Several studies have found some of the peptides in casein protein may have antioxidant properties. Lastly, taking casein protein may be beneficial for weight loss. More research is needed on these potential benefits.

Overall, casein protein appears to be beneficial for all the applications listed above. It has been studied extensively, and most manufacturer claims are backed up by real science. With that said, many of these same benefits can be obtained through dietary sources of high-quality protein.

Who Can Benefit from Casein Protein?

Casein protein is highly beneficial for a wide range of people. The groups that will notice the most benefits are:

  • Bodybuilders – Bodybuilders, weightlifters and other strength athletes will experience many benefits of casein protein. Anyone who lifts weights on a regular basis needs quite a bit of protein in their daily diet – so much so that it can become a challenge to meet that requirement with food alone. Casein powders are an affordable and easy way to increase your daily protein intake. Casein is particularly useful for use before bed, as it keeps your muscles fueled throughout the night. As a weightlifter, you want to remain anabolic at all times, and avoid entering a catabolic state at all costs. With a quick casein protein shake before bed, you can keep your muscles happy all night long with a steady stream of amino acids.
  • Athletes – Athletes of all types can benefit from adding a casein supplement to their diets. Whenever you use your body in a strenuous way – whether that’s with running, sports, weightlifting, or something else – you damage your muscles. With proper fuel, your muscles will recover and grow larger – and casein protein is the perfect fuel for muscle growth! Casein protein is the best type of protein powder for athletes wanting to recover faster and more efficiently.
  • Vegetarians – Vegetarians, and others on restrictive diets can benefit from casein protein. As someone who doesn’t eat meat and/or dairy products, it can be difficult to meet daily protein intake needs. Adding a casein protein can help. Keep in mind that, since it’s derived from milk, casein is not technically vegan – although it is vegetarian. If you’re looking for a true vegan protein powder, look for a good vegetable protein and/or soy protein blend.

How Do I Take Casein Protein?

Casein protein is best used for muscle recovery so, it’s good to take after workouts, and before bed to help fuel your muscles at night.

Most experts recommend that you take whey protein immediately following your workouts, because whey absorbs faster. This is beneficial because your body needs to absorb nutrients quickly following a workout.

Casein, on the other hand, takes several hours to digest which makes it a better choice for periods of time when you won’t be eating.

Many weightlifters like to use casein protein before bed, because of the unique casein benefits and slow-digesting properties.

This is really the best way to use these supplements. Having a quick casein shake before bed will help keep a steady stream of amino acids flowing to your muscles for up to 7 hours.

To sum up, casein protein is best used in between meals and before bed.

Lastly, we recommend using a BlenderBottle to mix your casein shakes – it’s much easier than using a clunky blender!

Are There Any Side Effects of Casein Protein?

People often ask us about any potential casein protein dangers or side effects. In general, there’s not much to worry about when taking casein. Some people do experience some side effects, as detailed below:

  • Upset Stomach

Some people experience an upset stomach and/or gassiness when taking casein protein powders. If you find this happens to you, try having your casein shake after a meal and not on an empty stomach.

  • Allergic reactions

A small percentage of people are allergic to casein protein and/or the other ingredients used in these supplements. Allergies can be minor to severe, resulting in anything from upset stomach to vomiting to rashes. If you have an allergic reaction to ANY supplement, stop taking it immediately.

There are more possible side effects for consuming too much protein in general, but that doesn’t apply specifically to casein protein. In general, there are very few casein protein dangers or side effects to be worried about.

To avoid any potential side effects, we recommend that you always follow the dosage instructions on the product packaging. Do not take more than the recommended amount, unless you run it by your doctor first. This applies to ANY supplement you take.

Note: We do not recommend taking any supplements featured on this website without speaking with a doctor first.

How Do I Pick a Good Casein Protein Powder?

In order to find the right casein protein powder for you, you’ll have to weigh your options. There are a TON of different products out there. Be sure to look at these key factors, explained below:

  • Quality of Ingredients – what type of casein protein is used? Micellar casein, casein hydrolysate, calcium caseinate, etc? What type of sweeteners are used? Are there any unnecessary ingredients? The casein product you choose should generally be a simple, clean formulas with a solid dose of protein and not much else.
  • Amount of Protein – how much protein is in each serving? The majority of our top recommendations include around 20-30g in each serving, so look for that ballpark.
  • Value for Money – how much does the product cost per serving? Be sure to calculate on the actual per serving cost (or per gram of protein cost), rather than just comparing the price of two different packages. While you don’t necessarily want cheap casein protein, you don’t want to spend more than necessary.
  • Taste/Texture – how does the product taste? Does it mix easily? It can be difficult to tell, so we recommend reading user reviews to get a feel for how people like the taste. Also make sure to get a flavor that you actually like.
